{The players follow a master game in the London System until Ben introduces a
new, simple move 11…Nxd2 leaving White’s King in the center. The
middlegame develops normally until Ben’s startling P-sac 23…e5!? The only
trouble is it is not wholly sound…Black recovers his P but his K is exposed
on the semi-open h-file and his Ng7 hemmed by White’s pawns e5/g3. White
misses 30.Nh6+ leading to a winning endgame and further compromises her Q
position with 32.Qh3? Sensing her attack is disappearing she strikes out with
an exchange sac 33.Rxh5 but this is simply unsound and Black catches her with
a neat tactic 35…,Bf3 wins a piece.} 1. d4 d5 2. Bf4 Nf6 3. e3 e6 4. Nf3 Bd6

{In King’s Indian Defence, both players vary from the classical path with
6…Na6; 7.g4 By move 12 a typical unbalanced position is reached where it is
hard to judge who is better or the best way of continuing. For sure, Black’s

{Bruce transposes from his English to Panov-Botvinnik Attack against Caro-Kann,
a line which promises a slight but persistent edge for White. By move 24 an
interesting and equal Q&B vs. Q&N ending arises. Nathan unwisely opens the
position 26…f6? and the white Q dominates the Center. In answer to an
annoying check White interposes his Q, 33.Qd4, confident he can win the
resulting K&P ending…but he can’t -it is a draw! Black too miscalculates
the possible ending and declines the exchange. Bruce now finds the correct
plan of advancing his K-side pawns with 38.Kh4 and wins cleanly.} 1. c4 c6 2.
